High-End Computing Program

Delivering high-end computing systems and services to NASA's aeronautics, exploration, science, and space technology missions.


If you are a NASA-sponsored scientist or engineer, computing time is available to you at the High-End Computing (HEC) Program's NASA Advanced Supercomputing (NAS) Facility and NASA Center for Climate Simulation (NCCS).

02.12.21 - Transition to RMS from eBooks for ARMD, HEOMD, STMD, NESC on February 26
On February 26, the following Mission Directorates will transition from the eBooks web-based management tool for requesting and managing access to HEC resources to a new tool called the Request Management System (RMS): Aeronautics Mission Directorate (ARMD), Human Exploration and Operations Mission Directorate (HEOMD), Space Technology Mission Directorate (STMD), and NASA Engineering and Safety Center (NESC).
